Weed management in landscaped areas can be challenging. Weeds may need to be controlled for public safety, fire reduction, aesthetics, and elimination of harborage for other pests. While many nonchemical options for controlling weeds exist—such as physical removal with tools, steam, flame or steam devices, grazing animals, and others—there are some situations that may require the application of herbicides.
For decades, glyphosate has been a common active ingredient used to control weeds in both agricultural and nonagricultural settings. However, there has been significant public concern about the use of glyphosate and other herbicides due to their potential...

Where is rodenticide exposure in wildlife coming from? Is it from use by residents or farmers? Applications by marijuana growers? Or from applications by qualified and trained structural pest control professionals? These questions are being asked by state legislators and regulators, special interest groups, and state pest associations across the country.
However, even though we don't fully know where all the exposure is coming from, action is already being taken to restrict the use of rodenticides in urban areas. In 2020, California legislators placed a moratorium on almost all uses of second-generation anticoagulant rodenticide. And local jurisdictions have also added restrictions to rodenticide use. For example, in...

Licensing for perimeter spraying under California's pest control laws is dependent on the situation and site (Table 1). Structural Pest Control Board (SPCB) licensees, Department of Pesticide Regulation (DPR) Qualified Applicator License (QAL) holders, and DPR Qualified Applicator Certificate (QAC) holders are all legally allowed to make perimeter spray applications to control ants and other pests immediately around structures. However, the intent of these applications determines the specific license needed.
SPCB licenses
If the perimeter spraying is performed to prevent the entry of ants or other insects into the structure, then a structural license is required. If the pests are coming from the lawn, then the...
/h2>If your company does residential landscape pest control, your employees should be trained to know what to do when they encounter a vegetable garden, or fruit or nut trees in a yard (Figure 1). Their training should include how to answer a customer's questions about the safety of their pesticides around vegetables or herbs. Talking to a customer about the edible plants in their garden so you don't accidentally spray their plants might save that account from subsequent cancellation.
Is it appropriate for a technician to recommend that a resident simply wash their vegetables after having their yard treated for say, mosquitoes, or should the vegetables be thrown away? What about a perimeter spray around the home? The answer...
